Compare any two graphics cards:
Radeon HD 6750 vs Radeon HD 6850
IntroThe Radeon HD 6750 features core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6850, which uses a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 960 SPUs along with 48 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6850 should be 100% faster than the Radeon HD 6750 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6850 is quite a bit (approximately 43%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)
Pixel RateThe Radeon HD 6850 should be a lot (approximately 114%) more effective at anti-aliasing than the Radeon HD 6750, and capable of handling higher resolutions without slowing down too much. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
